They must think the shooter's heading home, in a hurry, to Montgomery County, VA. You almost have to go through the mixing bowl to get there.
Montgomery County is in MD, directly north of DC.
This is an area with many beaucoup AlQaida sympathizers, and up until 9/11 had resident what may only be described as a large AlQaida support team (60+ taxicab drivers who disappeared on 9/11).
Kasi, due for execution in mid-November, used to come here to work on fixing taxicab breakes. He normally visited every Saturday morning.
If this guy is AlQaida related, this is where you might find him!
